量子秘密共享理论研究

On the Theory of Quantum Secret Sharing

Daniel Gottesman

摘要:

我提出了量子秘密共享理论的各种结果。我证明了任何混合态量子秘密共享方案都可以通过从纯态方案中丢弃一个份额而得到,并且量子秘密共享方案中每个份额的大小必须至少与秘密的大小一样大。我表明,唯一的限制存在的量子秘密共享方案与一般的访问结构是单调性(如果一组授权,所以是更大的集)和不可克隆定理。我还讨论了使用量子态共享经典秘密的一些方面。在这种情况下,每个份额的大小有时可以是经典秘密大小的一半。

英文摘要:

I present a variety of results on the theory of quantum secret sharing. I show that any mixed state quantum secret sharing scheme can be derived by discarding a share from a pure state scheme, and that the size of each share in a quantum secret sharing scheme must be at least as large as the size of the secret. I show that the only constraints on the existence of quantum secret sharing schemes with general access structures are monotonicity (if a set is authorized, so are larger sets) and the no-cloning theorem. I also discuss some aspects of sharing classical secrets using quantum states. In this situation, the size of each share can sometimes be half the size of the classical secret.
